16:10 → 16:15 WP15: protection in UJ22

Speakers: Davide Bozzini (CERN), Francesca Paola Nicoletti (CERN)

Collimator/beamline protection

Procedure for shortening of metallic beam in UJ22

For magnet transport : protective scaffolding over collimator and beamline on TI2 side

Activity responsible : Davide Bozzini, Jean Louis Grenard, Maria Perez Ornedo

RQF3790608 - Request Scaffolding for bat: 3214 (UJ22) (requested 12-06-2026)

 

 

For cutting metallic bar : No need for scaffolding

• for performing the activity : a cherry picker will be used.
• for the protection of the machine : Installing scaffolding would present a higher risk than carrying out the activity itself; therefore, no scaffolding is planned. Instead, alternative risk mitigation measures will be implemented. 

Activity responsible : Jordi Bossy

16:15 → 16:20 WP19: FRAS installation phase

Speaker: Vincent Thomas Barbarroux (CERN)
